LAMP SHADE. OR REFLECTOR Specification of Letters Patent. Patented J an.21, 1919.

Application filed June '28, ms. Serial No. 2,430.

To all whom it may concern}.

Be it known that I, ISAAC Lmson, a citi- -zen of the United 'States ofAmerica,residlamps, bracket lamps, etc., and the object ofmy inventionis to provide an improved construction by which the shade or reflectormay be readily adjusted in different directions and held in adjustedposition.

In the accompanying drawing,

Figure 1v is a longitudinal section through a shade in '.which myinvention is embodied in one form; v

Fig. 2 is a section on the line 2-2, Fig. 1;

Fig. 3 is a broken plan view of a portion of the shade; I

Fig. 4 isa dropped perspective of aportion of the shade;

. Fig. 5 is a side elevation showing the shade detached from its standand in posi- 'tion for packing.

While the present fitting may be attached Y to a wire conduit or othersuitable support in any desired type of installation, I have here shownit applied to a desk stand having, as shown in Fig. 5, a base 10withwire conduit 11 rising therefrom and terminating in agoose neck 12.The base '10 is apertured at 13 to admit the wire cable 14 to theconduit 11, through which it rises to the fitting.

The fitting comprises a nipple 15 freely sleeving over the end of. andclosing the goose neck 12. The bushing 16, which passes through thelower side of the nipple, secures beneath its head 17 an arcuatesupporting plate 18, which is thus rigidly connected to the nipple. Thetrough-like shade proper- 19, transversely slotted at 20 'to accommodatethe bushing 16, rests upon this plate 18, and its upper portion, whichconforms substantially in curvature to that of the plate, isfrictionally'held between the latter and the nipple 15. A channelmolding 21 secured to the inner face of the plate 18 by plate 18, formsa. passageway 24.- for the wires14; which enter from the conduit 12 axisparallel to or coinciding with the longitudinal axis of the fitting.

The adjustment of the shade 19 around its longitudinal axis is readilyaccomplished (Fig. 2) by merely turning it around its axis against theresistance of its frictional engagement between the supporting plate 18and the nipple 15, and its adjusted position is automatically maintainedby this frictional engagement. The slot 20 obviously limits the extentof this movement. Its angular adjustment in a plane at right angles tothe axis bf the nipple 15 is secured by swiveling the nipple on the endof the goose neck 12. The extremity of the latter is cut of the bushing16 and, at the same time, to

limit the extent of angular adjustment in i this direction. A set screw27, taking into the goose neck 12 and passing through a slot 28 in thenipple 15, holds the latter in fixed position. The surface of the nippleadjacent the slot 28 may be knurled at 29 to render the grip of the setscrew secure.

When the stand is to be packed for shipping, it is merely necessary totake out the set screw 27, remove the nipple 15 carrying the lamp shade,and draw out a sufiicient length of the cord 14 to permit the fitting tobe positioned beneath the goose neck, where it maybe wrapped and securedagainst. in-

jury in a compact parcel. To assemble the fitting for use, it is onlynecessary to replace the nipple 15, draw down the wire cable 14,

and insert the set screw 27. After having. adjusted the reflector in itsdesired position,

the set screw is tightened and the parts are ready for use.

It will be observed that the transverse adjustment of the fitting aroundtheaxis of the socket causes no displacement of the wire cable whatever.Furthermore, the tilting of the reflector as a whole in the plane of theaxis of the lamp (Fig. 1), imparts a relatively slight twist to thecable at the point of its emergence from the bushing 16, and this twistis taken by the. cable at a point at which there is such free lengththereof that there is no possibility of injury to the latter.

'Moreov'er,. if desired, a smooth insulating bushing may be inserted inthe inner end of the bushing 16 to protect the wire cable from injuryand to insulate the metal parts from contact in case the cable should,by. any cliance', become worn. The construction is both simple andefficient, economically manufactured, conveniently shipped andassembled, and the few parts that it comprises are rugged andsubstantial.

Various modifications in detail of construction will readily occur tothose skilled in the art, and I do not limit myself to the precisestructure shown, which may be variously modified without departing fromwhat I claim as my invention.

I claim l p 1. An electric fitting comprising a troughlike shade, anarcuate supporting plate therefor, a nipple secured to said plate andbetween which and said plate the shade is frictionally gripped withfreedom of angular adjustment around its longitudinal axis, togetherwith a support on which said nipple 1s swiveled and means for securingsaid nipple in adjusted position.

2. An electric fitting comprising a troughlike shade, an arcuatesupporting plate there for, a nipple secured to said plate and betweenwhich and said plate the shade is fricing and having its axissubstantially coincident with the axis of the shade.

3. An electric fitting comprising a tubular support, a nipple adapted toswivel on said support, means for holding the nipple in adjustedposition, an arcuate plate rigid with one side of said nipple, and atroughlike shade frictionally gripped between said plate and nipple withfreedom of angular adjustment around its longitudinal axis,substantially as described.

In testimony whereof I have signed my name to this specification.

ISAAC LIB-SON.
